“Landsat offers a globally consistent data set with a short enough revisit time to allow us to consider the percent of time that surface water is present on an annual and seasonal basis, while its 30 meter resolution also enables detection of smaller ponds and rivers, providing greater connectivity.”

“The resolution of Landsat imagery and the size of the Landsat database enables critical insight for scalable, high resolution flood detection in several key ways… This increased resolution is particularly critical in urban areas.”

“The Deltares Aqua Monitor is the first global-scale tool that shows at 30-m resolution where water is converted to land and vice versa. With assistance from Google Earth Engine, it analyzes satellite imagery from multiple Landsat missions, which observed Earth for more than three decades, on the fly.”

“With the full Landsat record available, we can finally look at really big problems, like the global carbon cycle.”

“I don’t think people appreciate just how revolutionary it was when the Landsat archive became available for free and really empowered researchers and advocates to have access to that data at an affordable price to be able to do the kind of mapping that’s now been done, making visible what was previously invisible…”

“Landsat is the crown jewel of Earth Observation datasets—unique 40+ year archive.”

“I would summarize Landsat 8’s science impacts in three ways: More data, better data, and improved, expanded applications.”

“As the global population surpasses eight billion people, it will be important to effectively manage land to sustain life on Earth. Landsat 9 will pair with Landsat 8 to greatly improve our understanding of what is driving changes to our lands, surface waters, and coasts, and how we can sustainably manage it.”
